Contradictions are a natural occurrence in society. You can't build communism within capitalism neatly like that, but it doesn't inherently mean that those contradictions are bad, or make the person doing them automatically bad. Which is why it depends on the context. For instance, is it a real estate agency that has the hammer and sickle on the logo, or is it more like an actual communist literature bookshop? I think this question is more interesting than the vagueness of contradiction.
